Guide beam for incremental launching construction of steel box beam
The invention provides a guide beam for incremental launching construction of a steel box beam, which comprises two parallel main longitudinal beams and a connecting truss for connecting the two main longitudinal beams, each main longitudinal beam comprises a fixed beam and a variable-section truss beam, the fixed beam is used for being fixed with a guide beam embedded part at the front end of the steel box beam, the section of the variable-section truss beam is gradually reduced from the end close to the fixed beam to the end away from the fixed beam, an L-shaped connector is arranged at the end, away from the fixed beam, of the variable-section truss beam, the long edge of the L-shaped connector extends in the length direction of the main longitudinal beam and is located on the upper side of the short edge of the L-shaped connector, and the short edge of the L-shaped connector is fixed to the end of the variable-section truss beam. The steel box beam is guided to be placed on the pier through the guide beam, deviation correction in the pushing process is facilitated, the L-shaped end is arranged at the end of the guide beam, the guide beam can be conveniently erected on a front temporary pier when the guide beam moves forwards, and a stress point is provided for jacking when the front end of the guide beam scratches downwards.
本申请提供一种钢箱梁顶推施工用导梁，其包括两根平行设置的主纵梁及连接两根主纵梁的连接桁架，每根主纵梁包括固定梁及变截面桁架梁，固定梁用于与钢箱梁前端的导梁预埋件固定，变截面桁架梁自靠近固定梁的一端朝远离固定梁的一端的截面逐渐减小，变截面桁架梁远离固定梁的端部设有L型接头，L型接头的长边沿主纵梁的长度方向延伸且位于短边的上侧，其短边与所述变截面桁架梁的端部固定。通过导梁引导钢箱梁上墩，便于顶推过程中的纠偏，在导梁端部设置L型端头，可在导梁向前移动时，便于搭设在前方临时墩上，为导梁前端下挠时顶升提供受力点。
